Human HSD17B1 encodes 17β-HSD (17β-hydroxysteroid dehydrogenase type 1), a key oxidoreductase that catalyzes the conversion of estrone to the more potent estrogen estradiol and contributes to local steroid hormone homeostasis. By regulating estrogen/androgen balance, 17β-HSD integrates into steroidogenic and endocrine signaling pathways that influence transcriptional programs controlling cell proliferation, differentiation, and metabolism. Altered HSD17B1 activity or expression has been associated with hormone-dependent pathophysiology and dysregulated estrogen signaling in multiple tissues. As a result, HSD17B1 is widely studied in models of steroid metabolism, receptor-driven gene regulation, and endocrine-related disease mechanisms.
17β-HSD Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the HSD17B1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within HSD17B1. When directed to adjacent sites on opposite DNA strands, the two nickases generate offset single-strand nicks that together produce a staggered double-strand break, requiring coordinated on-target activity from both guides. The resulting DNA break is resolved by endogenous cellular repair pathways, most commonly through non-homologous end joining (NHEJ), leading to insertions or deletions that disrupt HSD17B1 function. By requiring dual sgRNA engagement at the target locus, the double nicking approach enhances editing specificity and provides a complementary CRISPR strategy for applications where additional control over targeting precision is desired.
To support efficient identification of edited cells, one plasmid encodes GFP for fluorescent visualization of transfected populations, while the companion plasmid carries a puromycin resistance gene for antibiotic selection. Together, these features support efficient enrichment of co-transfected populations and simplify the validation of HSD17B1-disrupted clones.
